The weight (mg) is balanced by the normal reaction acting on the body.
But What is the reason for this force(normal reaction)?

Fightfish said:Yes, it is conventional that we give the proton the positive charge and the electron the negative charge.
The normal reaction force is the force that a surface exerts on an object that is in contact with it. It is always perpendicular to the surface and acts in the opposite direction of the force applied by the object.
The normal reaction force is equal in magnitude to the weight of the object. This means that if the weight of an object increases, the normal reaction force will also increase.
The normal reaction force can be measured using a force sensor. The object of interest is placed on the sensor and the reading on the sensor will display the normal reaction force.
Balancing weight is important because it helps ensure that an object is stable and does not tip over. Understanding the normal reaction force is crucial in balancing weight as it determines the distribution of weight on the surface.
The normal reaction force is affected by the weight of the object, the angle at which it is placed on the surface, and the surface material. Other factors such as friction and air resistance may also play a role in the normal reaction force.
